Question

我有一个带有单选按钮的标准form_for，它们没有将值传递给params。

这是表格（减去额外内容）：

<%= form_for(switch) do |f| %>
  <%= f.radio_button :referrer, 0, checked: true, class: 'di' %> 
  <%= f.label :referrer, "Facebook", class: 'di mr20' %>

  <%= f.radio_button :referrer, 1, class: 'di' %>
  <%= f.label :referrer, "Email", class: 'di mr20' %>

  <%= f.radio_button :referrer, 2, class: 'di' %>
  <%= f.label :referrer, "Through a charity", class: 'di mr20' %>

  <%= f.radio_button :referrer, 3, class: 'di' %>
  <%= f.label :referrer, "Other", class: 'di mr20' %>

  <%= f.submit "SWITCH NOW" %>
<% end %>

在params中它识别出引用者的存在，但不保留值："referrer"=>""

输出的HTML看起来很好：

<input type="radio" value="0" checked="checked" name="switch[referrer]" id="switch_referrer_0"> 
<label for="switch_referrer">Facebook</label>

<input type="radio" value="1" name="switch[referrer]" id="switch_referrer_1">
<label for="switch_referrer">Email</label>

<input type="radio" value="2" name="switch[referrer]" id="switch_referrer_2">
<label for="switch_referrer">Through a charity</label>

<input type="radio" value="3" name="switch[referrer]" id="switch_referrer_3">
<label for="switch_referrer">Other</label>

我已经阅读了7-8个关于此的其他问题并且没有找到解决方案，所以任何帮助都会很棒。

干杯
